5 Signs Your Diesel Engine Needs a Performance Facelift

November 30, 2021

If you’re a diesel owner, you already know why diesel engines are so much better than petrol engines: they’re more reliable, offer superior torque and power, and tend to perform better in rugged driving environments. The price tag attached to your ride was nothing to glance over, either, as these cars are usually more expensive than their petrol counterparts.

Why, then, does it feel like your diesel is mutinying? Are there days where the horses under your hood start performing more like ponies? Are you tired of putting the pedal to the metal, only for your engine to provide nothing short of a sluggish response?

If this sounds like your car, your diesel may be experiencing some issues – but it’s nothing Just Autos can’t remedy with the right performance upgrade! Keep reading to find out about the 5 signs your diesel engine needs a performance facelift.

1. Putting Your Foot Flat on the Accelerator Does Almost Nothing

This is one of the biggest signs that your diesel engine is starting to lose its thrill. Firstly, due to the fact that diesels are built for torque rather than horsepower, it can be difficult to find an abrupt amount of power right away – but if you’re accelerating and your foot is on the floor with nowhere near as much speed being created as you would expect, it’s a sure sign that all is not well.

When this happens to your car, the chances are high that your turbocharger isn’t performing anywhere near its potential due to a lack of fuel flowing through the engine. Replacing certain standard parts on your diesel with performance alternatives can deliver impactful results, and help keep your engine running healthily.

2. Your Mileage Has Started Decreasing Vastly

One of the major advantages to having a diesel over petrol is that fuel consumption tends to be better with diesels because they’re built for power rather than speed. However, if over time you’ve found yourself spending more and more each week on fuel for no apparent reason, it’s likely that your engine is starting to experience performance issues.

Before you assume it must be something to do with the car itself, we’d recommend checking that all of your tyres are in good shape and have enough tread on them – if they don’t, this could cause a fair bit of extra friction each time you put the pedal down, which will mean more fuel being used.

3. There Are Black Plumes of Smoke When You Drive

One of the best ways to make sure your diesel is performing at its full potential is to keep an eye on what comes out when you drive. If, when you’ve been driving for a while or just accelerating in general, smoke starts coming from your exhaust pipe, there’s definitely something wrong.

Are the clouds of black smoke streaming from your car making it difficult to see behind you? Do they seem especially pungent? If so, one of the best things you can do is take your vehicle to Just Autos straight away – we’ll let you know exactly what’s going on! Our team can also find the right performance upgrade replacement that’ll have you falling in love with your diesel all over again.

4. The Engine Doesn’t Sound Quite Right

Another surefire sign that something isn’t right with your diesel engine is if the noise it makes doesn’t sound quite right. Specifically, a major indication that your diesel needs some TLC is if there’s a banging or clattering noise coming from the engine bay when you accelerate – this means something isn’t going smoothly, and could be as minor as a lack of lubrication or as major as damage to one of the internal components.

Ensuring that you service your vehicle regularly and stay up to date with maintenance is one of the easiest ways to prevent mechanical failure. If you’ve maintained your engine and are confident that everything is running as it should be, but are still experiencing performance issues, bring your vehicle into Just Autos’ workshop to let our team find a solution.

5. Your Car Struggles Going Up Inclines

Does your diesel struggle to keep going when you’re trying to get up an incline? It might be a small problem such as the turbocharger not working well enough because of a lack of fuel supply, or it could be something like a clogged fuel filter, which in turn results in insufficient fuel being delivered to the engine.
